Scientists have identified a link between tea consumption and longevity
Regular consumption of tea, especially green tea, contributes to the prevention of cardiovascular diseases, obesity, diabetes and certain types of cancer. This was reported on June 9 by Science Daily magazine.
A team of scientists from the Tea Research Institute of the Chinese Academy of Agricultural Sciences, led by Mingchuan Yang and Li Zhou, analyzed the effect of Camellia sinensis tea leaves on human health. According to experts, the drink has a neuroprotective effect and is able to slow down the loss of muscle mass in the elderly.
The main benefit is due to the high content of polyphenols, in particular catechins. Studies have shown that regular tea consumption reduces the risk of overall mortality and improves cholesterol levels. According to the researchers, green tea plays a crucial role in the prevention of cardiovascular diseases, neuroprotection and has antimicrobial activity.
The scientists emphasized that catechins help control weight and improve metabolic parameters in obese people. In addition, those who constantly drink tea are less likely to have biomarkers of Alzheimer's disease and cognitive impairment.
At the same time, the researchers drew attention to the risks associated with the use of commercial beverages. Bottled tea and bubble tea (tea with tapioca balls) often contain artificial sweeteners, preservatives and excessive amounts of sugar, which can negate all the beneficial properties of the product. Microplastics and pesticide residues have also been found in some samples, which may pose a threat if consumed in large quantities over the long term.
Additionally, experts pointed to the tea's ability to interfere with the absorption of non-heme iron and calcium. This factor is important to consider for vegetarians and people with specific dietary needs. Experts recommend giving preference to moderate consumption of traditional freshly brewed tea to achieve maximum health benefits.
Gastroenterologist Tatiana Golovchanskaya, in an interview with Izvestia on March 29, spoke about the health risks of herbal teas. She shared that such teas are often perceived as a "safe alternative." However, the specialist clarified that herbal teas can contain a variety of components, including leaves, flowers, seeds, roots and fruits of various plants, which may contain flavanoids, organic acids, polysaccharides, essential oils and other substances. Golovchanskaya stressed that on paper it all sounds like a chemical factory under the guise of "health from nature."
